I don't have a family history of cancer but I was worried about whether I have colorectal cancer. So what are my chances of getting colorectal cancer?

Under age. 50, about 4/100, 000. After age 50, it goes up sharply. Unless you have ulcerative colitis, multiple polyps, or any condition that increases your chances, you don't need to have a conlonscopy until age 50.
